The data packet Pkc may further include a pairincluding attribute data for a domain name of a server and a value ofthe attribute data.

The AP apparatus 400 may receive network setup related information fromthe home appliance 200 and transmit network related information to thehome appliance 200 in response thereto.

The home appliance 200 receives network related information. The networkrelated information may include at least one of port information, TCP/IPinformation, MAC address information, network identifier information(service set identifier (SSID)), etc. of the AP apparatus 400.

The Wi-Fi application 274 of the home appliance 200 receives networkrelated information and accesses the AP apparatus 400 using the receivednetwork related information under control of the controller 270.

The memory 240 stores the received network related information forfuture use.

If the smart grid related indicator 630 operates such that the homeappliance enters the network setup mode, the smart grid relatedindicator 630 may be turned on with a first pattern, that is, blink, instep S715 among steps S710 to S720.

The network connection related indicator 610 is turned off during stepsS710 to S720.

In step S725 in which the home appliance 200 accesses the AP apparatus400, the network connection related indicator 610 may be turned on withthe first pattern and the smart grid related indicator 630 may be turnedon with the second pattern. The first pattern may mean blinking and thesecond pattern may mean that the indicator is constantly turned on.

Next, the home appliance 200 determines whether product registrationwith the server is completed (S730) and transmits the product relatedinformation to the server (S735) if product registration is notperformed. Then, the home appliance receives a product registrationcompletion message from the server (S740). Steps S730 to S740 correspondto steps S830 to S840 of FIG. 8, respectively.

The controller 270 of the home appliance 200 may attempt to performproduct registration with the server through separate user input.

Alternatively, the controller 270 of the home appliance 200 may transmitproduct related information to the server after accessing the APapparatus 400.

For example, the communication unit 222 may transmit the network setuprelated information before accessing the AP apparatus 400 and transmitthe product related information after accessing the AP apparatus 400.

The network setup related information includes port information of thecommunication unit 222 and the product related information may includeat least one of a product id, a device name and a device password.

The communication unit 222 may transmit a single packet per event. Forexample, when a server product registration event occurs, for productregistration with the server, attribute data for a product id, a devicename, a device password or a server domain name and a value of theattribute data may be grouped and transmitted.

The communication unit 222 may receive a product registration completionmessage from the server 500 when product registration with the server500 is completed. The received product registration completion messageis stored in the memory 240.

If product registration is attempted through user input in a state inwhich product registration is completed, the controller 270 may notperform product registration based on the product registrationcompletion message stored in the memory 240.

If the network setup event occurs, as shown in (a) of FIG. 10b , thehome appliance 200 may transmit a data packet Pka including attributedata for port information and a value of the attribute data to the APapparatus 400. In the figure, one data packet Pka includes a pair ofattribute data and a value of the attribute data.

When a server registration event occurs, as shown in FIG. 10(b), thehome appliance 200 may transmit, to the AP apparatus 400, a data packetPkb including a first pair pa1 including attribute data for portinformation and a value of the attribute data, a second pair pa2including attribute data for a product id and a value of the attributedata, a third pair pa3 including attribute data for a device name and avalue of the attribute data and a fourth pair pa4 including attributedata for a device password and a value of the attribute data as a singledata packet. The data packet Pkb may be transmitted to the server 500unlike (a) of FIG. 10 b.

The data packet Pkb may further include a pair including attribute datafor a domain name of a server and a value of the attribute data.

As another example, the communication unit 222 may transmit the networksetup related information and the product related information before andafter accessing the AP apparatus 400. The communication unit 222 maytransmit address information of the server when the product relatedinformation is transmitted.

When a network setup event occurs, as shown in (a) of FIG. 10c , thehome appliance 200 may transmit, to the AP apparatus 400, a data packetPkc including a first pair pa1 including attribute data for portinformation and a value of the attribute data, a second pair pa2including attribute data for a product id and a value of the attributedata, a third pair pa3 including attribute data for a device name and avalue of the attribute data and a fourth pair pa4 including attributedata for a device password and a value of the attribute data as a singledata packet. The data packet Pkc may further include a pair includingattribute data for a domain name of a server and a value of theattribute data.

When a server registration event occurs, as shown in (b) of FIG. 10c ,the home appliance 200 transmits the data packet Pkc. The data packetPkc may be transmitted to the server 500 unlike (a) of FIG. 10 c.

During steps S730 to S735, the network connection related indicator 610is turned on with the first pattern and the smart grid related indicator630 is turned on with the second pattern.

In step S740, since the home appliance 200 is connected to the server400, the network connection related indicator 610 and the smart gridrelated indicator 630 may be turned on with the second pattern, that is,may be constantly turned on.

Next, the home appliance 200 determines whether wireless networkdisconnection continues for a predetermined period (S745) andre-accesses the AP apparatus based on the received information ifwireless network disconnection does not continue (S750). Steps S745 toS750 correspond to steps S845 to S850 of FIG. 9, respectively.

The home appliance 200 attempts to re-access the AP apparatus 400 for apredetermined time (e.g., 2 minutes), if the home appliance istemporarily disconnected from the AP apparatus 400. The home applianceattempts to access the AP apparatus 400 based on the network relatedinformation of the AP apparatus 400 stored in the memory 240.

The home appliance 200 decides that the home appliance is disconnectedfrom the AP apparatus, that is, remains in a non-connection state, ifthe home appliance is disconnected from the AP apparatus 400 for thepredetermined time or more.

In step S745, the home appliance 200 may turn the network connectionrelated indicator 610 and the smart grid related indicator 630 on withthe first pattern (blinking) if the home appliance is temporarilydisconnected from the AP apparatus 400 for the predetermined time.

Unlike the figure, in step S745, the smart grid related indicator 630may be turned on. At this time, blinking of the network connectionrelated indicator 610 in step S745 is preferably different from blinkingin steps S725 to S735. That is, different first patterns may be used.

More specifically, a ratio of on timing to off timing of the networkconnection related indicator 610 in steps S725 to S735 may be 1:1 but aratio of on timing to off timing in step S745 may not be 1:1.Accordingly, the user may identify temporary disconnection of thenetwork.

Since the home appliance re-accesses the server in step S750, similarlyto step S740, the network connection related indicator 610 and the smartgrid related indicator 630 may be turned on with the second pattern,that is, may be constantly turned on.

When the wireless network is disconnected for a predetermined time ormore, the network connection related indicator 610 and the smart gridrelated indicator 630 are turned off.

A state in which the communication unit 222 of the home appliance 200does not receive the network related information from the AP apparatus400 may be referred to as an un-provisioned state, a state in which thecommunication unit 222 of the home appliance 200 attempts to access theAP apparatus 400 is referred to as a provisioning state, a state inwhich the communication unit 222 of the home appliance 200 receives andstores the network related information regardless of connection with theAP apparatus 400 is a provisioned state, and a state in which thecommunication unit 222 of the home appliance 200 isconnected/disconnected to/from the AP apparatus 400 is a referred to asa connected/disconnected state.

A state in which the communication unit 222 of the home appliance 200 isnot registered with the server 500 is referred to as an un-registeredstate, a state in which the communication unit 222 of the home appliance200 attempts to access the server 500 is referred to as a registeringstate, a state in which the communication unit 222 of the home appliance200 is initially registered with the server 500 is referred to as aregistered state, and a state in which the communication unit 222 of thehome appliance 200 is connected/disconnected to/from the server 500 isreferred to as a connected/disconnected state.

FIG. 11 is a flowchart illustrating a method for operating a homeappliance according to another embodiment of the present invention, andFIGS. 12 to 13 b are views referred to for describing the operatingmethod of FIG. 11.

The communication unit 222 of the home appliance 200 periodicallytransmits a check signal to the accessed server (S905) and receives aresponse signal corresponding to the check signal from the server(S910). Steps S905 to S910 correspond to steps S1005 to S1010 of FIG.12, respectively.

More specifically, the communication unit 222 of the home appliance 200may transmit the check signal every minute.

The check signal may be a heartbeat signal and the response signal maybe a response signal to the heartbeat signal.

The home appliance 200 may transmit a single data packet includingattribute data for an appliance status and a control lock status and avalue of the attribute data as a check signal and receive a responsesignal from the server 500.

FIG. 13a shows the case in which a check signal Sch is output from thehome appliance 200 and is transmitted to the server 500 via the APapparatus 400 and a response signal Sre is output from the server 500and is input to the home appliance 200 via the AP apparatus 400.

Next, the home appliance 200 determines whether the response signal isnot received for a first predetermined time and, if so, retransmits thecheck signal (S920). Steps S915 to S920 correspond to steps S1015 toS1020 of FIG. 12, respectively.

The controller 270 of the home appliance 200 retransmits the checksignal when the response signal is not received for the firstpredetermined time. The first predetermined time may correspond to 2minutes, for example. When the check signal is transmitted every 1minute, the controller 270 of the home appliance 200 may retransmit thecheck signal when the response signal is not received twice.

The retransmitted check signal may be a heartbeat signal.

Alternatively, the retransmitted check signal may include a single datapacket including attribute data for a home appliance status and acontrol lock status and a value of the attribute data.

FIG. 13b shows the case in which a retransmission check signal Sreq isoutput from the home appliance 200 and is transmitted to the server 500via the AP apparatus 400 and a response signal Smsg is output from theserver 500 and is input to the home appliance 200 via the AP apparatus400.

After retransmission, the home appliance 200 determines whether theresponse signal is not received for a second predetermined time (S925)and, if so, determines that connection with the server is broken (S930).The home appliance 200 re-accesses the server based on the receivedinformation (S935). Steps S925 to S935 correspond to steps S1025 toS1035 of FIG. 12, respectively.

The controller 270 of the home appliance 200 determines that the homeappliance is disconnected from the server 500 when the response signalis not received for the second predetermined time. The secondpredetermined time is preferably less than the first predetermined time.In order to check the connection state immediately after retransmission,the second predetermined time is preferably set to be short. Forexample, the second predetermined time may correspond to 1 minute. Thecontroller 270 of the home appliance 200 determines that the homeappliance is disconnected from the server 500, when the response signalis not received for 1 minute, that is, when the response signal is notreceived once.

When connection with the server 500 is broken but is connection with theAP apparatus 400 is maintained, as described above, the networkconnection related indicator 610 may blink and the smart grid relatedindicator 630 may be constantly turned on.

FIG. 14 is a flowchart illustrating a method for operating a homeappliance according to another embodiment of the present invention, andFIGS. 15 to 16 b are views referred to for describing the operatingmethod of FIG. 14.

The home appliance 200 determines whether a first reset mode is set(S1105) and, if so, breaks the connection with the AP apparatus (S1110).Then, the network related information of the AP apparatus stored in thememory is deleted (S1115). Steps S1105 to S1115 correspond to stepsS1205 to S1215 of FIG. 15, respectively.

For example, when the smart grid related indicator 630 is pressed for atime Ta (e.g., 5 seconds) in a state in which the home appliance 200 isconnected to the AP apparatus 400 in step S725 or is connected to theserver 500 in step S740, the home appliance 200 may be in ade-provisioned state as the first reset mode (local reset mode).

The controller 270 of the home appliance 200 controls the communicationunit 222 to break the connection with the AP apparatus 400 in the firstreset mode and controls deletion of the network related informationreceived from the AP apparatus 400 and stored in the memory 240.

Thus, the communication unit 222 of the home appliance 200 may break theconnection with the AP apparatus 400 in the first reset mode, as shownin FIG. 16 a.

The network connection related indicator 610 and the smart grid relatedindicator 630 may both be turned off. The smart grid related indicator630 may blink three times before being turned off.

Next, if the first reset mode is not set in step S1105, step S1120 maybe performed.

That is, the home appliance 200 determines whether a second reset modeis set (S1120) and, if so, transmits a deletion request signal forproduct related information to the server (S1125). Then, the homeappliance may receive a deletion completion message from the server(S1130). Steps S1120 to S1130 correspond to steps S1220 to S1230 of FIG.15, respectively.

For example, if the smart grid related indicator 630 is pressedpredetermined times (e.g., 5 times) for a time tb (e.g., 10 seconds) ina state in which the home appliance 200 is connected to the server 500in step S740, the home appliance 200 may perform the second reset mode(factory reset mode).

In the second reset mode, the communication unit 222 of the homeappliance 200 may transmit a deletion request signal Sreq_de to theserver 500 and receive a deletion completion signal Smsg_de from theserver 500, as shown in (a) of FIG. 16 b.

Next, the home appliance 200 breaks the connection with the AP apparatusS1135. Then, the home appliance deletes the network related informationof the AP apparatus stored in the memory (S1140). Steps S1135 to S1140correspond to steps S1235 to S1240 of FIG. 15, respectively.

In the second reset mode, the controller 270 of the home appliance 200controls the communication unit 222 to break the connection with the APapparatus 400 and controls deletion of the network related informationreceived from the AP apparatus 400 and stored in the memory 240, whenthe deletion completion message Smsg_de is received from the server 500.

The communication unit 222 of the home appliance 200 may break theconnection with the AP apparatus 400 in the first reset mode, as shownin (b) of FIG. 16 b.

FIG. 17 is a flowchart illustrating a method for operating a homeappliance according to another embodiment of the present invention, andFIGS. 18a to 18d are views referred to for describing the operatingmethod of FIG. 17.

The home appliance 200 determines whether a signal for entering thesmart grid mode is received (S1710), determines whether the homeappliance is connected to the AP apparatus 400 and the server 500(S1715) if the signal is received, and turns the smart grid relatedindicator 630 and the network connection related indicator 610 on withthe second pattern (S1720) if the home appliance is connected to the APapparatus and the server.

When the home appliance 200 is powered on and connected to the APapparatus 400 and the server 500, the smart grid related indicator 630may be constantly turned on by default. That is, the home appliance mayenter the smart grid mode. At this time, the network connection relatedindicator 610 may also be constantly turned on.

As shown in (a) of FIG. 18a , when the user presses the smart gridrelated indicator 630 in a state in which the smart grid relatedindicator 630 of the home appliance 200 is turned off, the smart gridrelated indicator 630 may be constantly turned on if the home appliance200 is connected to the AP apparatus 400 and the server 500. The homeappliance may enter the smart grid mode.

If the home appliance is not connected to the AP apparatus and theserver in step S1715, the home appliance 200 determines whether the homeappliance is connected to the AP apparatus but is not connected to theserver (S1725), and, if so, turns the smart grid related indicator 630on with the second pattern and turns the network connection relatedindicator 610 on with the first pattern (S1730). That is, in step S725,the network connection related indicator 610 may blink and the smartgrid related indicator 630 may be constantly turned on.

As shown in (b) of FIG. 18(a), when the user presses the smart gridrelated indicator 630 in a state in which the smart grid relatedindicator of the home appliance 200 is turned off, the networkconnection related indicator 610 may blink and the smart grid relatedindicator 630 may be constantly turned on if the home appliance 200 isconnected to the AP apparatus 400 but is not connected to the server500.

Next, after step S1720 or after step S1730, any one of step S1740, stepS1750 or step S1760 may be performed.

First, in step S1740, the home appliance 200 determines whether powerinformation is received from the server 500 (S1740) and, if so, turnsthe grid mode indicator on (S1745).

When the communication unit 222 of the home appliance 200 receives powerinformation such as a dr signal from the server 500 in the smart gridmode as shown in FIG. (a) of FIG. 18b , the grid mode indicator 620 maybe temporarily turned on as shown in (b) of FIG. 18 b.

The power information received by the home appliance 200 includes asingle data packet Sdr, the data packet Sdr may include set DR mode dataas attribute data, and a value of the attribute data may include aduration hour, a duration minute, an offset hour and an offset minute.

The home appliance 200 may pause at a time corresponding to a DR period(e.g., a peak time) based on the received power information andre-operate after the peak time. That is, the home appliance 200 mayoperate in the smart grid mode.

For example, according to the smart grid mode, the compressor of therefrigerator may be temporarily turned off and rotation of the tub ofthe washing machine may pause.

The power information signal received by the communication unit 222 fromthe server 510 may be divided into first power information and secondpower information. The first power information may correspond to asignal for saving power by 13% and the second power information maycorrespond to a signal for saving power by 50%.

Upon operation of the home appliance and, more particularly, the drivingunit 245, the controller 270 of the home appliance 200 may control thedriving unit 245 to continuously operate when the first powerinformation signal is received from the communication unit 222 andcontrol the driving unit 245 to pause and re-operate when the secondpower information signal is received from the communication unit 222.That is, when the second power information signal requiring more powerconsumption reduction is received, the driving unit may pause, therebyreducing power consumption.

The controller 270 of the home appliance 200 may control the homeappliance to operate in a power saving mode based on the first powerinformation signal when the first power information signal or the secondpower information signal is received from the communication unit 222,upon non-operation of the driving unit 245.

In step S1750, the home appliance 200 determines whether an overridemode is set (S1750) and, if so, turns the smart grid related indicatoron with the second pattern and turns the grid mode indicator off(S1755).

For example, as shown in FIG. 18c , when the override button 645 ispressed, the grid mode indicator 620 may be turned off and the smartgrid related indicator 630 may be turned on with the second pattern.

As another example, as shown in FIG. 18d , when the override button 645is pressed, the network connection related indicator 610 may blink andthe smart grid related indicator 630 may be turned on. Then, the networkconnection related indicator 610 and the smart grid related indicator630 may both be turned off.

The override button 645 may be a grid button included in the display230. Accordingly, when the grid button (not shown) is pressed in a statein which the grid mode indicator is turned on and the smart gridindicator is turned on, the override mode may be performed.

The override mode means that the home appliance 200 continuouslyoperates without pause even at the time corresponding to the DR time(e.g., the peak time) even when the power information is received fromthe server 500.

For example, the compressor of the refrigerator may continuously operatewithout pause or the tub of the washing machine may continuously rotatewithout pause even at the peak time, according to the override modewhich has priority higher than that of the smart grid mode.

In step S1760, the home appliance 200 determines whether a signal forterminating a smart grid mode is received from the server 500 (S1760)and, if so, turns the smart grid related indicator off (S1765).

The controller 270 of the home appliance 200 breaks the connection withthe AP apparatus 400, when a signal for breaking a connection isreceived.

At this time, the controller 270 of the home appliance 200 may transmita data packet corresponding to a power off event to the server 500before breaking the connection with the AP apparatus 400. Thetransmitted data packet is a single packet and may include a pluralityof attribute data such as a home appliance status, a remote controlstatus and a control lock status and a value of the attribute data.

FIGS. 19a to 19d are diagrams showing various data packets transmittablebetween the home appliance and the server.

According to the embodiment of the present invention, the communicationunit 222 of the home appliance 200 transmits or receives a single packetper event.

FIG. 19a shows the case in which the home appliance 200 receives refreshrequest data from the server 500 and FIG. 19b shows the case in whichthe home appliance 200 transmits a refresh data packet as a singlepacket in response thereto.

In particular, if the home appliance 200 is a drier or a washingmachine, a refresh data event occurs. Therefore, a plurality ofattribute data and values of the attribute data may be transmitted tothe server 500 as a single packet.
